ROOFING CLIP.

Application filed July 12,

To all whom it may concern.-

Be it known that we, VERNON J. HARWARD and WALTER P. Bum), citizens of the United States, residing at Durham, in the county of Durham and State of North Carolina, have invented certain new and useful Im provements in Roofing Clips, of which the following is a specification.

This invention relates to improvements in roofing clips.

The primary object of this invention is the provision of a roofing clip which is adapted for use in connection with the effective placing of shingles or composition roof in A further object of this invention is the practical type of roofing clip embodying a structure which will permit of its performing its main function, that of maintaining the shingle or roofing elfectively upon the roof, andembodying an. additional function in that the same will permit of relative movement of the pieces of roofing material, which is mainly important in shingle types of roofing, in that, incident to temperature variations the roof structure may shrink or the shingles or roofing expand or contract.

A further object of this invention is the provision of a roofing clip of the above mentioned character, substantially identical with the type of roofing clip shown in our copending application, Serial No. 638, 965, filed May 14,1923, and embodying material improvements thereover, in that the same will permit of contraction and expansion of the roofing materials or the roof upon which it is placed without sacrificing any of its inherent advantages.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts thruout the several views,

Figure 1 is a plan view of a roof, showing composition roofing shingles as placed thereon in cooperative relation with the improved clip herein set forth.

Figure 2 is a fragmentary cross sectional view, taken substantially on the line 2-2 of Figure 1, and showing the manner in which the improved clips are connected to the shingles and to the roof.

view, taken through an improved clip, showing the manner in which the same is cooperatively used in connection with shingles, prior to its final placement thereon.

Figure 4 is a perspective view of the preferred form of the improved shingle clip, this form of the invention beingconstructed of sheet material, such as zinc, tin, or galvanized metal. v

Figure 5 is a perspective view of a modified form of this invention, preferably constructed after the invention from wire.

In the drawing, wherein for the, purpose of illustration are shown preferred and modified forms of this invention, the letter A may generally designate the preferred form ofclip, which may be used in connection with the placement of sheets of roofing material B upon the roofing structure 0.

In lieu of the form of invention A, a clip F may be'used,which has some advantages over the formation of the improved clip out of sheet material.

Referring to the improved and preferred form of clip A, the same while preferably constructed of zinc, tin or other galvanized sheet material may be made of any material. It preferably includes a fiat or plane elongatedattaohing portion 10; which adjacent one end edge 11 thereof is preferably provided with a nail or fastener inserting opening 12; the opening 12 being continued longitudinally of the attaching portion 10, in a reduced slot or extension 13, contiguous with the opening 12 and extending toward the free edge 11. The opening 12 together with the reduced'elongated extension 13 thereof preferably forms a slot which ex tends longitudinally of the attachin portion 10, adjacent one end thereof. t the other end of the attaching portion 10, an arcuate front or connecting portion 15 is provided, which is integral with the attaching flat portion 10, and has also a retaining tab portion 16 formed integral therewith. The retaining tab 16, after the clip A has been manufactured, but before its' application upon a roof, for the major run thereof, is preferably plane and is disposed in acute angular relation with respect to the plane of the attaching portion 10; being connected to said attaching portion 10, as by the heretofore mentioned arcuate front portion 15. At the free end, the retaining tab 16 is bent downwardly, as at 17, in effect providing a flange or hook which, while of relatively ing cleat B therein,

' of course,

short plane formation maybe arcuate; it being most important that the same faces toward the plane of the attaching portion 10, and of course being bent transversely to the plane of said attaching portion 10, and preferably in acute angular relation with respect to the plane of said angular portion 10.

Referring. to the application of the improved clip A upon a roof G, the shingles D are placed upon each other and upon the roof G according to the alignment which they will assume by reason of positioning of the clips A. The clips A are placed substantially upon the roofing structure C, according'to the instructions contained in our (o-pending application, above referred to. To this end, the clips A are placed just rearwardly of the slot between the shingle stubs 26 of the composition shingles B so that the front edge of theclip A, as defined by the outer surface of the arcuate connecting portion 15 aligns substantially with the end edge 27 of a slot 25. The attaching por- 1 tion 10 of a clip so placed is then secured to the shingle B upon which itis placed and to the roof C substantially as is illustrated in the drawings, pending application above referred to. The superposed rows of shingles B are accurately aligned by placin the lower edges 29 of the shingle stub 26 thereof within the pockets provided intermediate the attaching portion 10 and retaining tab 16 of the clips A. This, 7 insures that the shingles will have all of the shingle stubs 26 thereof exposed for the same depth, which is essential to a uniformit of appearance.

After t e improved clip A has been assembled with a superposed 'shingleor roof-.

final operation, the improved shingle clip A will be placed substantiall as is illustrated in the fullcross sectiona lines in Figure 3 of the drawing. In this position the hook end 17 of the upper retaining tab. 16

will lie over the to surface of the uppermost roofing shingle.

he roofer, by simply hitting the retainin tab 16 a light blow with a hammer, will atten the retaining tab 16 over the top surface of the roofing piece B being applied, and in abutting relation therewith. During this flattening operation, the hook piece or flange 17 of the retaining tab 16 will first engage the roofing piece B and grip therein, and as the force of the hammer is fully applied, it will kick the arcuate front portion 15 of the roofin clip A outwardly from the front edge 29 o the shingle butt 26 which it receives, so that as is illustrated in dotted lines in Flgure 3 of the drawings, the g Y the run of the board, which of course buc les the slotted arrange forward ed e 29 of the shingle butt would be in consi erable spaced relation with the arcuate front portion 15 of the clip A. This space 30 permits the shingle B and more and as set forth in our co-- and preparatory to the and the retaining ta particularly the butt portions 26 thereof to expand, to decrease shingle will not buckle transversely. It is the common fault .of all roofing clips which are attached to the lower end-0f the shingle that the same will not permit the shingle to expand. However, with the improved clip A, the shingle or roofing pieces B may be assembled upon theroofing structure 1n facile manner, and in proper alignment priiicipally.by means of the clip A; said clips during the final placing movement thereof being automatically extended to permit of expansion and contraction of the shingles. The elongation of the openings in the atan elongated opening 41 therein. Side arms 42 and 43 are bent from the loop portion into substantially parallel relation and at each side of the loo portion 40; said arms 42 and 43 prefera ly lying in the same plane with the ends, and opposite the loop 40, the arms 42 and 43 are arcuated, as at 44"and 45 respectively, providing retaining extensions 46 and 47 respectively, which correspond to the retaining tab 16 of the preferred form of clip A. At their free ends the retaining portions 46 and 47 of the arms "42 and 43 are downturned, as at 48 and 49 respectively, transversely to the run of the arms 42 and 43. The planes 43 with their upturned retaining portions 45 the space 30 so that the taching piece or portion 10 of the clip A also I loop portion 40. At their free defined by the arms 42 and and 46 are transversely to the planes in roofing clip has been provided, which is ada tedto effectively place and maintain roo ng shingles or pieces upon a roof structure without crow ing the lower edge of the superposed shingle. Very often [several lines or rows of clips are placed upon the same roofing board. The roofing board, subsequent to placing of the roofing, in a ood many instancesshrinks transversel of the roofing. However, ment of the attachingtab of the roofing clip, structure of the same,

description of this end an overturned retaining shorter than said attaching will permit of this shrinking of the roofing board and expansion or contraction of the shingles, without liability of buckling or stretching of the shingles or roofing pieces. It provides a very flexible roofing structure.

Various changes in the shape, size and arrangement of parts, may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the'scope of the claims.
